Definitions

  • the invention relates to an electric plug-in connector, including a trough-shaped socket unit and a plug unit being fittingly insertable into the socket unit;
  • the socket unit having a plug channel with an elongated, approximately rectangular cross section being defined by longer longitudinal side walls and shorter transverse side walls and being closed off at an inner end thereof by a bottom from which a multiplicity of plug pins protrude at right angles;
  • the plug channel of the socket unit having recesses in the longitudinal side walls defining a clear opening or enlarged internal diameter approximately in a middle region;
  • the plug unit having a substantially rectangular cross section with longitudinal lateral surfaces, transverse lateral surfaces and a front closure surface in which insertion openings are formed for the passage of the plug pins therethrough to plug sockets located behind them;
  • the transverse lateral surfaces being guided along the transverse side walls and the longitudinal lateral surfaces being guided on guide segments of the longitudinal side walls, upon insertion of the plug unit into the socket unit; respective safety ribs extending in the insertion direction in the vicinity of two
  • an encoding rib is formed onto one part, for instance the plug unit, while a complementary encoding groove is provided in the respectively other part, in that case the socket unit.
  • the plug unit can be introduced into the socket unit only with a predetermined alignment, on the condition that the latter has a corresponding encoding groove.
  • a plug-in connector comprising a trough-shaped socket unit and a plug unit to be fittingly inserted into the socket unit in a given insertion direction;
  • the socket unit having two end edges, a plug channel with an elongated, approximately rectangular cross section and a middle region, longer longitudinal side walls and shorter transverse side walls defining the plug channel, an inner end with a bottom closing off the plug channel, and a multiplicity plug pins protruding at right angles from the bottom;
  • the longitudinal side walls having recesses formed therein defining a given greatest clear opening or enlarged internal diameter approximately in the middle region of the the plug channel, and the longitudinal side walls having guide segments formed thereon;
  • the plug unit having a substantially rectangular cross section with longitudinal lateral surfaces, transverse lateral surfaces, a front closure surface and two end edges, the front closure surface having insertion openings formed therein for passage of the plug pins through the insertion openings to plug sockets located behind them, the transverse
  • the safety ribs may be recessed from the front closure surface of the plug unit by a distance that is less than the safety margin of the plug pins. This recessing of the safety ribs assures that the corresponding safety grooves in the longitudinal lateral surfaces of the socket unit only need to be guided to a lesser extent into the depth of the plug channel. The relatively deep safety grooves thus only slightly reduce the stability of the socket unit.
  • the safety ribs of one lateral surface each have a different spacing relative to the end edges of these lateral surfaces.
  • the safety ribs attain a kind of additional encoding to prevent incorrect polarization even when the plug is inserted straight.
  • At least some of the safety ribs are formed onto an encoding rib in the form of protrusions.
  • At least some of the safety ribs are formed onto a closure plate slipped onto the plug unit.
  • FIG. 1 is a diagrammatic, side-elevational view of a plug unit
  • FIG. 2 is a bottom-plan view of the plug unit, as seen in the direction of the arrow II in FIG. 1;
  • FIG. 3 is a fragmentary, longitudinal-sectional view of the plug unit, which is taken along the line III--III of FIG. 2, in the direction of the arrows;
  • FIG. 4 is a longitudinal-sectional view of a socket unit, which is taken along the line IV--IV of FIG. 5, in the direction of the arrows;
  • FIG. 5 is a bottom-plan view of the socket unit.
  • a plug unit 1 which has a housing 2 that has a substantially rectangular cross section, at least in a lower portion 2a thereof.
  • the lower portion 2a is defined at an outer periphery by longitudinal sides 3 and 4 and transverse sides 5 and 6.
  • a front end, in terms of a plug insertion direction, is defined by a closure surface 7 that has a number of insertion openings 8, only a few of which are suggested in FIG. 2.
  • the housing 2 has an interior with a hollow chamber 9 into which socket strips can be thrust, from the left in FIG. 1.
  • the socket strips have plug sockets each being disposed behind a respective one of the insertion openings 8.
  • An introduction opening for the socket strips is closed off in the present example by a closure plate 10 that can be slipped on.
  • a cable supply channel 11 is also formed onto the top of the plug unit 1.
  • the plug unit also has an encoding rib 12, that is known per se, on one end.
  • a socket unit 20 shown in FIGS. 4 and 5 has a housing bottom 21 that has a number of plug pins 22, only a few of which are suggested in FIG. 5.
  • the height of the plug pins 22 is represented in FIG. 4 by dot-dashed lines 22'.
  • the plug pins 22 are enclosed by an encompassing collar of the socket unit, which is formed by two longitudinal side walls 23 and 24 and two transverse side walls 25 and 26. These walls thus form a plug channel 27 into which the plug unit 1 can be inserted.
  • the plug unit 1 is guided with its transverse lateral surfaces 5 and 6 along the transverse side walls 25 and 26, and with its longitudinal lateral surfaces 3 and 4 along guide segments 28, 29, 30 and 31 of the socket unit 20.
  • Encoding grooves 32 which are provided in the socket unit 20 correspond to the encoding ribs 12 in the plug unit 1, so that even with a vertical insertion and a correct alignment, only the proper plug unit can be introduced into the socket unit.
  • the encoding rib Since the encoding rib is located only on the right-hand side of the drawing in the example shown, it does not prevent an incorrect, crooked insertion of the plug unit which leads with the left-hand end edge as seen in the drawing. Although the plug unit naturally cannot then be inserted all the way, nevertheless the plug pins 22 can be damaged. This is all the more true for the example shown since a recess 33 is provided in the longitudinal side wall 23 between the guide segments 28 and 30 and a recess 34 is provided in the longitudinal side wall 24 between the guide segments 29 and 31, in the socket unit. These recesses create space for a non-illustrated locking device between the socket unit and the plug unit. In that case, the plug unit could even be inserted with the coding ribs 12 leading and crooked.
  • additional safety ribs 35, 36, 37, and 38 are formed onto each side of the end regions of the longitudinal side walls 3 and 4 of the plug unit.
  • the plug unit is given a width on the ends that in each case is greater than the greatest clear opening or internal diameter of the plug channel 27 between the recesses 33 and 34.
  • Corresponding safety grooves 45, 46, 47 and 48 in the socket unit are associated in complementary fashion with the aforementioned safety ribs 35, 36, 37, 38. As can be seen from FIG.
  • the safety ribs 35 and 36 on one end of the plug unit and the safety ribs 37 and 38 on the other end of the plug unit each have a different, slight spacing from the respective end edge or from the respective transverse lateral surfaces 5 and 6. Thus they assure that the plug unit cannot be inserted vertically after being rotated by 180°.
  • the additional safety grooves 45, 46, 47 and 48 reduce the thickness of the wall of the receiving part in the vicinity thereof, it is desirable for these grooves not to be made overly deep. For that reason, in the present example the safety ribs 35-38 are not extended as far as the closure surface 7 but rather are recessed by a certain spacing distance, and thus the safety grooves 45-48 need not be very deep, either. However, this spacing of the recessed safety ribs must not be any greater than the spacing between an upper closure edge 39 of the side walls 23 and 24 and the upper ends of the plug pins 22, which are suggested by the dot-dashed line 22' in FIG. 4. This assures that even though the plug unit can be inserted crooked to a certain depth, nevertheless it cannot endanger the plug pins 22.
